I specifically do remember the chap saying "I would never have my PPD off leash".
I'm sure there are plenty of people who feel the same way about their own dogs. I'm equally sure there are also plenty of people who have no problem letting their PPD dogs off leash, around other people, etc.
It's really a case-by-case basis that depends on the training and behaviour of the dog and the handler's comfort level of letting that dog be off-leash.
Geographical location (read: laws) will also play a huge role, but since you're based in Nicaragua, I'll venture a guess and say that you likely don't have to worry about that as much as someone in the US/Canada.
Here in Canada, if someone breaks into your house and gets bit by your dog, they'll sue you and you'll be the one in trouble, with a good chance of the dog being put down. Doesn't make much sense, but that's how it is.
I didn't see anything in that video that was overly impressive. Between the music, the dramatic fading of text, and the editing, the whole thing stank like a trailer for another one of Michael Bay's Transformer movies.
The dogs had great obedience and bit on command, which is nice, but they only showed a few seconds of every "fight" and no instances of the dog releasing (out'in) and continuing obedience after being called off and still being pumped up and in drive. You don't want a dog that you can't control after giving the bite command.
I recently came across this old thread: https://www.germanshepherds.com/forum...y-monkeys.html
. Flip through the pages and you'll see YouTube videos (like in post #56) of dogs that can actually
mess someone up. (Read the descriptions - some of those dogs have zero protection training at the time of the video being taken.) That level of commitment to the fight is what I'd want to see in a PPD.
